There has to be an adopter out there for Andy.  Andy is a older gentleman who gets along with dogs but can be weary of some men.   Once Andy trusts you, he loves you and is a faithful companion.    Andy was found as a stray with a chain dragging behind him and tested positive for heartworm.  He was likely an outside dog living his life at the end of a chain.   Share Andy far and wide so we can make the rest of his precious life is better than the first 8 years.   Metro Detroit area.
